AI-suggested

Upgrade Glances to version 4.5.6 or later, where this vulnerability is fixed. Until then, restrict write permissions to the cache file path (~/.cache/glances/glances-version.db or $XDG_CACHE_HOME/glances/glances-version.db) to trusted users only. No other vendor advisories indicate alternative mitigations.

Description

Glances versions prior to 4.5.6 contain an insecure deserialization vulnerability in the version cache file handling. The application uses pickle.load() to deserialize a cache file stored at a predictable and world-accessible path without integrity or format validation. An attacker with write access to this cache file can execute arbitrary code with the privileges of the user running Glances. This issue is fixed in version 4.5.6.
